The angle between the magnetic meridian and geographical meridian is called
Angle of dip
Angle of declination
Magnetic moment
Power of magnetic field
The angle of dip is the angle
A short magnetic needle is pivoted in a uniform magnetic field of strength $1 \,T.$ When another magnetic field of strength $\sqrt 3 \,T$ is applied to the needle in a perpendicular direction, the needle deflects through an angle $\theta$, where $\theta$ is....$^o$
Due to the earth's magnetic field, charged cosmic ray particles
Angle of dip is $90^o$ at
The magnetic field of earth is due to
